For an nxn matrix a, explain how to find each value. (a) the minor mij of the entry ajj take the determinant of the nxn matrix that is left after deleting the ith row and ſth column. take the determinant of the (n - 1) (n - 1) matrix that is left after deleting the jth row and jth column. take the determinant of the (n - 1) (n - 1) matrix that is left after deleting the ith row and jth column. take the determinant of the n xn matrix. take the determinant of the (n − 1) (n-1) matrix that is left after deleting the ith row and ith column. (b) the cofactor cij of the entry aj • cij = mij if i + j is negative, then cij = -m; j. if i + j is positive, then cij = mijo cij = -mij if i + j is odd, then cij = mij. if i + j is even, then cij = -mije if i +j is odd, then cij = -mj. if i + j is even, then cj = m; j. (c) the determinant of a. o a| = 211c12 + 212c11 + + 21nin o|a| = 211c11 + 212-12 + + aincin a| = 211c11 - 312c12 + - 21cin o|a| = 211c11 - 212c12 - - 21cin o|a| = 211c11 +222c22 + + ann con

Find the coordinates of point x that lies along the directed line segment from y(-8, 8) to t(-15, -13) and partitions the segment in the ratio of 5: 2.

Do, h = (7, 9) (14, 18) the scale factor is

Design an er diagram for keeping track of information about votes taken in the u. s. house of representatives during the current two-year congressional session. the database needs to keep track of each u. s. state's name (e. g., texas', new york', california') and include the region of the state (whose domain is {northeast', midwest', southeast', southwest', west'}). each congress person in the house of representatives is described by his or her name, plus the district represented, the start date when the congressperson was first elected, and the political party to which he or she belongs (whose domain is {republican', democrat', 'independent', other'}). the database keeps track of each bill (i. e., proposed law), including the bill name, the date of vote on the bill, whether the bill passed or failed (whose domain is {yes', no'}), and the sponsor (the congressperson(s) who sponsored - that is, proposed - the bill). the database also keeps track of how each congressperson voted on each bill (domain of vote attribute is {yes', no', abstain', absent'}). additional information:
